How can you measure axial displacement of turbine?

Axial displacement of a turbine can be measured using a non-contact displacement sensor, such as a laser displacement sensor or an eddy current sensor, which provides precise readings without interfering with the turbine's operation. Alternatively, dial gauges or linear variable differential Transformers (LVDTs) can be used to measure the axial movement by directly contacting the turbine components. It's important to ensure that the sensors are properly calibrated and positioned to accurately capture the displacement during turbine operation. Regular monitoring helps in assessing the turbine's condition and preventing potential failures.
